OIL-PRESS BOJL Specification of Letters Patent.

Patented July 10, 1906 Application filed March 2, 1908. Serial No.303,399.

To all whom, it may concern:

Be it known that l, Josnrn H. HUBBELL, a. citizen of the United States,residing at Dayton, in the county of Montgomery and State of ()hio, haveinvented new and useful imrovements in Oil-Press Boxes, of which theollowing is e. specification.

This invention relates to oil ress boxes.

One of the primary objects 0 the invention is the provision of a box ofthe character set forth having means for the removal of therem-block'and mat superimposed thereupon, by virtue of which the mat canhe seps;

rated from the ram-block and the ram-block three parts mentioned.

In'the drawings accompanying and forming a part of this s ecifieation Ishow a simple form of embo 'ment of the invention, which, to enablethose skilled in the art to practice said invention, I will fully setforth in the following description, while the novcity of the inventionwill be included in the claims succeeding said desori tion.

The press-box shown in the drawings'ineludes in its make-up asupporting-plate, as 2. The plate 2 has on its opposite sides and at thefront thereof flanges, eeoh designated by 3, and which suhserve theircustomary function. In addition to these flanges 3 the plate is providedwith the customary pend- .Iliitin'the met or Fig. 2 is a front elevationof the box with a portion of the marginal flange thereof removed. Fig. 3is a rear elevation' of the same. 4 is s top plan view of one therearedge t ereof slots, as 6, shown as being two in number, although this isnot essential. In the slots are fitted lugs, as 7, two, of course, ofsaid lugs being illustrated, the lugs when the ram-block is 1n operativeposition serving to bear against the bottoms of the respective slots 6to interlock the rear end of the said ram-block with the supporting orbase plate 2. The lu s are not s own as being an integral part 0 theplate 2,-elthough, if reqfuired, the may be. In the present case astenindevices. unite the shanks or bodies of the ugswith the supporting-plateand these fastening devices may consist of screws, belts, or rivets, asmay be desired.

The mat which'iits u on the ram-block 5 consists of a perforate andlongitudinally and transversel corrugeted plate 8, and to this extent itto lows the construction of cer tain mats at present in use. The rearend of the mat has an interlocking connection with the ram-block, forwhich purpose the mat is shown as .rovided with hcok-sha ed lugs 9 toenter t e slots 6 in the rear 0 the ramblock. The slots are shown asintersected by; vertical recesses 10, which receive fins 1 l on therespective lugs 7, although this is not essential. The fins 11 may'havea snug fit in the recesses 10, so as to more firmly mainerforated plate8 against lateral motion. t the front end of the box the iii ait'S andram-block 5 are held in clamping relation with the supporting-plate, and

iii this purpose I have shown a sm ie clampmember, such as 12, through te hub or body of which is feeeiy passed a screw, as 13, ta ped into theplste 2. From the inner sid s of the clsmping member 12 there extends arejection, as 14, which passes through a ole or erforation 15 in thependent apron 16 at the front end of the met 8. On the inner side of theapron 16 is a lug 1?, fittin an a'erture 17 in the front the of ram lockw on the parts are assembled to ole 15 extends through this lug. Fromthe outer side of the clamping member there is pendent the leg 18, whichbears solidly against the up or side of the supportingplate 2 and a soabuts against the front flange 3.

When the parts are in working relation in a press, the lugs 7 on theplate 2 will be disposed in the slots 6 of the ram-block 5, while thelugs 9 on the mat 8 will be also in said. slots, the apron or flange 16at this time over lying the front face of the ram-block. The projection14 will be in the hole 15, so that when the screw 13 is tightened upsaid projection 14 will bear down solidlv upon the apron 16, drawing thesame, and hence the mat and ram-block, in solid relation with the plate.In view of the way the ram-block and mat are held in operative positionthere is no possibility of their being accidentally displaced or movingin any direction. The head of the screw 13 is so shaped as to receive awrench, so that the screw can be easily turned.

To separate the mat and ram-block from the supporting-plate, the screw13 is taken from lace to permit the removal of the clamping member 12.The mat or plate 8 is then raised sufficiently to carry the apron orflange 16 clear of the ram-block or grate 5, after which the mat can beeasily separated from the ram-block by ushing the same rearward. Toremove t e ram block or rate, it is moved forward sufficient to free itrom the lugs 7.

The removal of the mat and the ram-block is one that can be quickly andeasily accom plished for any purpose without removing the box from theframe of the ress. The ram-block and mat are detac ably associated withtheir supporting-plate to secure the result in question; but when inoperative relation they are held solidly in position by simple andeffective means, involving in the present case a clamping device whichis readlly accessible.

What I claim is 1. An oil-press box comprising a supporting-plate, aram-block on the supportingplate, a mat on the ram-b1ock, the ram-blockand mat being detachably associated with the supporting-plate, and meansfor holding the ram-block and mat in assembled relation with thesupporting-plate.

2. An oil-press box involving a supporting- 1 plate, a ram-blockinterlocked at one end with the su porting-plate, a mat on the ramblock,inter ocked at the same end with the ram-block, and clampin meansoperative a ainst the o posite end 0 the mat and ramb ock to hold themin solid relation with the supporting-plate.

3. In an 011-press box, a supporting-plate, a

rain-block having an interlocking connecttion at one end with thesupporting late, a mat on the ram-block, having an inter ockingconnection at the same end with the ramblock, and clamping meansdirectly engaging the mat to clamp the mat and ram-block to thesupporting-plate.

4. In an oil-press box, a su )portinglate rovided with lugs, aIHlll-blOGli in whic 1 the ugs are adapted to be fitted, a mat on theram-block, having lugs to enter the ramblock, the several lugs beinglocated at one end of the mat and ram-block, and means operative againstthe opposite end of the mat and ram-block to clamp the same to thesupporting-plate.

5. In an oil-press box, a supporting-plate having lugs, a ram-block onthe supportingplate to receive the lugs, a mat having lugs to enter theram-block, the several lugs being located at one end of the ram-blockand plate, the opposite end of the mat being provided with a dependingapron having a hole, and a clamping member connected with thesupporting-plate and having a projection to enter the hole to clamp theram-block and mat to the supporting-plate.

6. In an oil-press box, a su porting-plate having lugs, a ram-block on t1e supportingplate arranged to receive said lugs at one end thereof, amat on the ram-block having lugs at the same end to enter the ram-blockand provided with a depending apron at the other end having a hole, aclamping member bearing against the supporting-plate and rovided with aprojection to enter the hole and a headed screw to extend through theclampiiig member and tapped into the supportingate.

p 7. In an oil-press box, a su porting-plate having lugs, a ram-block ontlie supporting plate arranged to receive said lugs at one end thereof,a mat on the ram-block havin lugs at the same end to enter the ram-blocand provided with a dependin apron at the other end having on its innerace a lug and also having a hole, the ram-block being rovided with anaperture to receive said astmentioned lug, a clamping member bearinagainst the supporting-plate and rovide with a projection to enter theho e and a headed screw to extend throu hthe clamping member and tappedinto t e supportinglate.

p In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
